I posted a graphical setup I got at the time a little bit further down the topic but it isn't up-to date for what I'm using.
Also I'm using a lot of little texture mods which cover only one or two things. My go to list I use everytime, just search for the names on Nexus:
install in that order and let overwrite
1. Static Mesh Improvment (SMIM)
2. Nobel Skyrim SSE +SMIM Patch
3. Skyland
4. Blended Roads
5. RIS- Real Ice and Snow
6. Embers
7. HD Ultimate Fire effects
8. Deadly Spell impacts
9. Daedra-tastic Rune Spells
10. For Trees either use Enhanced Vanilla Trees on Nexus if u want stay close to vanilla or use https://lhmods.com/mods/lhs-forests-of-dibella-hd-uhd/# from an author who isn't on the Nexus anymore...u have to make an account thought
11. Rustic Clothing
12. Rustic Animated Potions and Poisons
13. Rustic Cooking
14. Bellayse Animal and Creature Pack
15. Bellayse Dragon Replacer
16. Realistic Water 2 ...I installed the optional watercolor in the installer as well
17.NPCS : Use this one https://www.nexusmods.com/skyrimspecialedition/mods/5291 and your npcs will not look like dolls...
18. Children: https://www.nexusmods.com/skyrimspecialedition/mods/2650 lot's of patches needed but worth it...if u want no hassle https://www.nexusmods.com/skyrimspecialedition/mods/22789 use this one
19. For lighting use Relighting Skyrim + ELE
20. Finally for a weather mod i use vivid weathers .. it has an option in the installer to install an optional filter called "Nextgen" or something... i think if u use that u didnt even need an ENB which means more FPS

speaking about FPS all of the mods are textures with 2k which is the size of the vanilla textures... but they still  look 10 times better than what Bethesda did... so performance impact should be non existence with this one if u can run vanilla SSE at 60 FPS :)
